Overheating problem, with fan stopping randomly

My Acer laptop, seem to have a heating problem. The fan stops randomly and the machine froze with over heat, I believe. It can't even load windows OS, and gets hanged even before it loads. Can anyone help me with this issue.

Re: Overheating problem, with fan stopping randomly

I had same issue. I took the fan apart and cleaned it out Still locks
up while i was installing XP. I left the cover to access heat sink
open then use laptop cooler to blow on it directly, then able to
install XP. After XP was installed, the computer stay stable even with
cover back on.

Hope this helps..

If it's overheating it's possible that either there's a problem with the fan, or the fan/heatsink is clogged with dust. If you know how to open up the laptop you can do that and use a can of compressed air to clean it out which may solve the problem. If not you'll have to replace the fan.

Most likely cause would be overheating due to clogged fan intake/exhaust or failing fan. If you want to tackle yourself Google "disassemble Acer ______ laptop" (insers your model number). You can determine if overheating is likely by carefully blowing some canned air into the fan intake.

Overheating When the CPU overheats then it will shut down (i.e. thermal overload) and won't boot up again until it has cooled down. If this is the problem is not fixed then the CPU will eventually fail. A faulty fan causes the problem or the fan and heat sink assembly are clogged with dust. Check the CPU fan to see if it spins freely, if not replace the fan. If the fan and heat sink is clogged with dust the remove the dust and make sure the vents are clear and dust free. Use a small brush and can of compressed air to do this.

I
suspect that your cooling fan has stopped working or the sealing mating
between the fan surface and the CPU is not intact. These fans quit
working because dirt and grime gets into the fan shaft and friction
slows the fan . also if the fan gets accidentaly moved on the CPU, then
this breaks the heat transfer tape between the CPU. This over heating
causes the CPU to fail. Open the machine and observe if the fan is
running correctly.

while the computer is off use compress air and spray it into the ventilation area where the fan is that stopped working. hopefully this will free the dust to hopefully get the fan to start moving again.
If the compressed air does not work, you will have to replace the fan.

1. try cleaning all vents with compress air in order to remore dust and fuzz that can be cloging the vents.
Once this done, verify that fans works proprelly,(check air flow coming out of vents) if they dont they will need to be replace or cleaned out.

2. Check power supply unit, and battery.
Sometime power supply unit is defective, getting too hot and power output is not stable and shuts down the laptop. ( change power supply unit) check if battery hold charge. if not change battery

3. Check connections for looseness and contact

If all seems normal,and none of the mentionned point seem to be defective, the cause is deeper and would need to be looked at by a technician.

If there is some setting in BIOS to speed up the fan then its good, speed it up.

If not then place it on such a place from where your colling fan is "NOT" covered with anything.
Usually when the machine is in your lap, we accidently block the air flow path, and the machine starts to heat-up.
It has happened to me also.

It could be overheating, either you need to replace the fan, or at least open it up and remove any dust (bunnies) that may have built up inside, if your fan is gummed up it won't spin which then causes computer to overheat.

The overheating can be caused by :-
The fan has stopped working - needs replacing
The vents and or fan is blocked with dust - needs cleaning
When operating the laptop it needs to be placed on a flat surface so the vents on the bottom of the laptop are ubobstructed.
